Statistics Descriptive Statistics vs. Inferential Statistics

In this lesson, we are going to talk about descriptive statistics versus inferential statistics. First we need to distinguish how statistics is different from other mathematics. We will talk about how descriptive and inferential statistics separate. Finally, we are going to talk about populations versus samples and then we are going to put all of those ideas together and look at how population, samples, descriptive, and inferential statistics all fit together. Statistics is invented because we want to do better in science. We even have a special name for the scatter of measurements and that is called a distribution.

I am a student who is extremely weak in math. In order to be very strong in math, specially for engineering field, could you provide me with sequential order of mathematical topics and textbooks. With what should I begin so that I can master big topics like calculus, statistics, probability ... etc.

Your guidance is precious to me.

Thank you so much.

This is not specific, I feel like I am lost. I understand early part but the examples don't make sense. I mean basically I am lost in the examples.

Great lecture.

Is it possible for members to save your lecture slides?

Just to make sure I'm understanding this correctly, Descriptive Statistics is basically exact information (the type of information that we desire from a population, but are unable to obtain. Inferential statistics is the information that we gain from samples, and we then use that info in order to come to conclusions.

What specific areas of Math on Educator.Com should I brush up on in order be successful at Statistics, I have obtained an override to bypass lower level classes. But I need to know specifically what I need to review in order to do well. Please be very specific, Thanks
